Abstract
En mekanisme for beskyttet operativsystemoppstart som forhindrer skadelige komponenter fra å bli lastet med operativsystemet og derfor forhindrer avsløring av systemnøkkelen på feil grunnlag. Etter at en del av maskinoppstartsprosedyren har blitt gjennomført eksekverer operativsystemlasteprogrammet, lasteprogrammet blir validert, og en korrekt maskinstatus blir enten verifisert til å eksistere og/eller blir opprettet. Når lasteprogrammet er blitt verifisert til å være et legitimt lasteprogram, og maskinstatus under den det eksekverer er verifisert til å være korrekt, er lasteprogrammets fremtidig oppførsel kjent for å beskytte mot lastingen av skadelige komponenter som kan forårsake avsløringen av systemnøkkelen. Med lasteprogrammets oppførsel kjent for å være trygg for systemnøkkelen kan gyldighetsovervåkeren bryte forseglingen til systemnøkkelen og levere den til lasteprogrammet.
